Abstract Scope |
Dual-phase titanium alloys generally represent a good combination of strength and ductility. The deformation coordination between the α and β phases is the major mechanisms accounting for their load-bearing responses, the corresponding stress/strain distribution and thereby partitioning features, however, still remain elusive and deem detailed considerations. In this presentation, by investigating a Ti-Al-V-Fe (α+β) alloy, we aim to quantitatively elucidate the stress/strain partitioning characteristics with the assist of in-situ synchrotron X-ray diffraction experimentation. We will introduce here a theoretical framework in deriving the stress and strain tensor distribution of α and β phases, based on the two-dimensional diffraction patterns. By coupling these analyses with in-situ micro digital image correlation (DIC) technique, we will also discuss in detail about the role of stress/strain partitioning in the macroscopic deformation behavior. |
